Don't display menu on admin paths

I think the following issue would fix your problem.

Here's another solution. Add this to a custom module:

/**
 * Implements hook_mmenus_alter().
 */
function custom_mmenus_alter(&$mmenus) {
  // Disable on admin paths.
  if (path_is_admin(current_path())) {
    $mmenus['mmenu_left']['enabled'] = FALSE;
  }
}

Note that it's hook_mmenus_alter(), not hook_mmenu_alter(). The documentation in mmenu.api.php doesn't match the code, in this case.

Nevermind, my comment in #3 won't work. Here's a simpler patch which bypasses mmenu on admin paths.

I actually think if #2 would be commited would fix all these issues.

Thanks danilenko_dn and joelstein. The hook has been corrected to hook_mmenu_alter on the version 7.x-2.0.
So, now you can disable the mmenu on the admin page like this:

function hook_mmenu_alter(&$mmenus) {
  // Disables left mmenu on some specific pages.
  if (arg(0) == 'admin') {
    $mmenus['mmenu_left']['enabled'] = FALSE;
  }
}

With AMP, it would be nice to control which theme the mobile menu is inserted to. This does the trick for me.

function hook_mmenu_alter(&$mmenus) {
  // Disables left mmenu on some specific pages.
  global $theme;
  if ($theme != 'default_theme') {
    $mmenus['mmenu_left']['enabled'] = FALSE;
  }
}
